NeurOptics NPi-300 Pupillometer Gebrauchsanweisung Seite 5

If the NPi-300 Pupillometer is not in the Charging Station, to conserve battery life it will:
• Go into sleep mode after 5 minutes. To turn ON, touch the screen or push any button.
• Power down after 20 minutes.
Turning On the NPi-300 Pupillometer
• If the NPi-300 is out of the Charging Station and has powered down, press
(do not hold) the On/Off button
• If the NPi-300 is in the Charging Station and has gone to sleep, simply
remove from the Charging Station, and it will wake up automatically.
Setting Date and Time
To modify the date and time, from the Home
Screen, select the Settings icon
select Date or Time (Ex. 8). Follow the prompts
to input the current date (Ex. 9) and time (Ex. 10)
using 24-hour time configuration and select
Customers in the United States have the option
to enable Automatic Daylight Savings Time
(DST) in the Time settings. Automatic DST
is disabled by default. Automatic adjustments occur based only on US DST
regulations and are not updated according to geographic location, as the
NPi-300 is not connected to the internet or GPS.
Date and Time Maintenance:
• Regular quarterly maintenance is necessary to ensure date and time
are correct. The set date and time will affect the timestamp listed
for subsequent patient pupil measurements on the NPi-300 and
SmartGuard. Changing the date and time will not alter the timestamps
on previous measurements.
• Immediately adjust the time after any time change if Automatic DST
is disabled.
Returning to the Home Screen
Press the RIGHT or LEFT buttons (green circles) to return to the Home Screen (Ex. 11).
Measuring Pupils Using the NPi-300 Pupillometer
The NPi-300 provides objective pupil size and reactivity data independent of examiner – removing variability
and subjectivity. The NPi-300 expresses pupil reactivity numerically as the Neurological Pupil index, NPi (see
the Neurological Pupil index Scale below).

*A difference in NPi between Right and Left pupils of ≥ 0.7 may also be considered an abnormal pupil reading
